Quick question to see if anyone may be able to help me out. I just got done doing the calibration of the camera and it went well. I was able to capture 54 tags 11 times. I then did the camera alignment using tags and all 8 of those showed green and everything seemed aligned. But when i captured the picture and then placed some octogons down in certain area’s and burned them, then recaptured the photo they were way off. they seemed to burn just fine in the top left corner, but the bottom corners were way off and the center one is off just not as bad.
So I am curious is this just a normal thing with using cameras to burn things onto something?
Your image doesn’t look like it should. After calibrating and refreshing the window, your entire machine bed should be visible without any distortions.
That said, I calibrate my camera better manually than automatically with the tags, although in a very different spectrum to what you show. Manually calibrated I am under 0.5mm across 600x400mm (except in the middle, here I am at about 0.75+ mm), with April tags at about 1 - 1.5 mm.
this was picking the standard camera over the extended just do to the error rate. on the one is was .46 and on the standard it was .44.
But yes I agree that the the whole entire bed should be seen in the window. So not sure if there is something going on with falcon a1 pro and lightburn.
see here is one of the issue i run into running this calibration. they say to make sure it good and lite up but mine is washed out, with no way to change that in the software. and so because of that It wont find any of the tags. as you can see from this picture. only way I can get it too work is if I print the tags on more or less a 11 x 12 piece of paper. but then they seem way to big for the camera.
If you have made sure that your camera arrangement is “static”, i.e. cannot move at all which is the most important thing, then you should make yourself a good cup of coffee and start with lens calibration again and then continue with camera alignment. The LB camera system has improved over time but the road to easy and high quality and smooth camera handling is a long one.
I can often achieve relatively fine/usable results because I spend a lot of time on alignment and probably also have a slight handicap in going for the perfect for some things. (also applies to laser beam alignment )
I just saw your second picture. You are struggling with one of the main problems of the LB camera system - Light handling.
Find a piece of neutral material, not white, I use an MDF board that covers the entire work area. With that as a background you can do your lens alignment much better, honeycomb and camera are a bad mix.
Remember that you must not change the position of your camera alignment target graphic, (not to be confused with lens alignment) unless you can 100% re-establish the original position.
You should scale your April tags plate up to about 1/4 of your machine bed.
yeh I guess the calibration just does not work well with the A1 pro. Becuase i was able to capture 12 Images after I blocked out the light, and this is what it gives me now. as you can see from the snip its placing the background image like 1/4 above the 0,0. and again its not showing the whole bed. but in the camera view on the left it does.
maybe its best to just revert back to falcon design software where at least there software works with the camera. Until which time they are able to dial in the calibrtion. wasnt a loss though as i am currently just on the trial version anyhow.
thanks trying to help with it though, appreciate it.
